97 Yukon GT won't start

[Randazz0]

I want to say I wasn't getting the right mix of has and air because when I cleaned our the gunked up lines it worked, now I'm having am issue with the linkage for the transmission because the readout on the dash doesn't match what gear it's actually in. For instance if I'm all the way physically in first gear the dash shows I'm in 3rd

Not sure if this is your issue, but here is the adjustment procedure for a 98. Maybe it will help...

I'm going to give this a run tomorrow, just weird I think I have a dash from a diesel, doesn't the gas cluster have a max RPM of 6k? Because the one installed on my truck has 5k

It would say Diesel Fuel Only on it. It may be a 95, they showed up to 5k with a redline bar between 4 and 5k.

96 showed up to 6k with redline marks, 97/98 no redline markings.

Sounds like either bad gas but you said no spark I would check the grounds
Then check if the computer has power. Mice will get in and eat wires of sitting. Vehicles but make sure you have power going to your Coil
